Influence of flow properties on a structure of a mineral wool primary layer

Mineral Wool Primary Layer Formation in Collecting Chamber

“…Blagojević et al [15] used a multiple regression model to predict the primary layer homogeneity. The same kind of visualization setup was also used by Bajcar et al [16] and was followed by a computational fluid dynamics (CFD) analysis of the problem, confirming a significant effect of the local aerodynamic characteristics on the primary layer formation. Apart from the camera visualization, another possible method of primary layer structure analysis is by X-ray scanning, which is used mostly in the glass wool industry [11] and [17], although very little research work has been published so far.…”

“…Apart from the camera visualization, another possible method of primary layer structure analysis is by X-ray scanning, which is used mostly in the glass wool industry [11] and [17], although very little research work has been published so far. The method is based on radiation absorption and allows for the measurement of local primary layer densities, unlike the visualization method used in references [15] and [16], which can only provide information about the layer surface dynamics. To overcome the technical and confidentiality constraints of the industrial environment, a model study using the light absorption method is viable.…”

Preparation of Slag Wool by Integrated Waste-Heat Recovery and Resource Recycling of Molten Blast Furnace Slags: From Fundamental to Industrial Application

“…These previous studies investigated the preparation process of rock/slag wool [8] and the heat transfer properties using theoretical methods [8,9], or studied the different utilizations of slag wool as a reinforcing agent [10]. However, to the knowledge of the authors, the optimization of raw materials as well as a clean and energy-saving producing method for slag wool production has not been well investigated.…”

“…In consideration of the broad prospects of slag wool applications, several researchers have focused on this field in the past decade [8][9][10]. These previous studies investigated the preparation process of rock/slag wool [8] and the heat transfer properties using theoretical methods [8,9], or studied the different utilizations of slag wool as a reinforcing agent [10].…”

The Influence of Airflow Characteristics and Accumulation Grid Velocity on the Formation of a Stone Wool Primary Layer

“…Širok et al [1] showed that mineral wool fibres typically have aspect ratios in excess of 1000, leading to complex flows with mutual intertwining and breakage of fibres, and also inhomogeneous primary layer deposited on the accumulation grid. Other experiments and monitoring of production process in the stone wool industrial environment were conducted by Blagojević et al [12] and Bajcar et al [13] who developed quantitative measures for the monitoring of the primary layer quality.…”
